Abstract

Polyalkylene oxides are stabilized by a mixture of the following compounds: (a) a compound of the formula <FORM:1087567/C3/1> (b) a compound of the formula <FORM:1087567/C3/2> and (c) a compound of formula R4SnR5, wher R is alkyl, aryl, or heterocyclic, R1 is alkyl, aralkyl, cycloalkyl, aryl, or heterocyclic, A is S or CH2, R2, R3 are alkyl of 1 to 4 carbon atoms, n is 1 to 4, and R4, R5 are alkyl or -(CH2)m-COOR6, where R6 is an alkyl and m is 1 to 4. Suitable polyalkylene oxides are those obtained by polymerizing saturated alkylene oxides, halo-substituted epoxides, e.g. epichlorohydrin, cycloaliphatic epoxides, or epoxy ethers, e.g. methyl glycidyl ether, or by copolymerizing saturated with unsaturated epoxides e.g. glycidyl acrylate. Typical examples of compounds (b) are bis(4-hydroxy-2-methyl-5-t.-butyl-phenyl) methane and bis(4-hydroxy-2, 5-di - t. - butyl-phenyl)sulphide. Typical examples of compounds (c) are di(octadecyl)sulphide, di-(dodecyl) tetrasulphide, and tetrasulphide (diacetic acid octadecyl ester). The stabilizer may be added as a solid or in solution. The stabilized polymers may be dissolved or caused to swell, and may be cross-linked. Swelling agents or solvents are dimethyl formamide, tetramethylene sulphone, dioxane, methanol, aromatic hydrocarbons and chlorinated hydrocarbons. Soots, fillers, dyes or pigments, extender oils or lubricants may also be added. The example describes the stabilization of a methanolic solution of 100 parts of a mixture of propylene oxide-allyl glycidyl ether copolymer, thiourea, silicic acid, zinc oxide, dipentamethylene thiuram-tetrasulphide, 2-mercaptobenzothiazole and titanium dioxide with a mixture of 2 parts of each of three compounds of Formula (a) in which R is methyl and R1 is 3-ethoxybenzothiazole, 1,2,4-triazole, or imidazole, 1/2 part of bis(4 - hydroxy - 5 - t. - butyl - 2 - methylphenyl) sulphide, and 1/2 part of di(octadecyl)-disulphide. The resulting polymer was spun and the filaments cross-linked.
